Algorithm:

  • STEP 1: START
  • STEP 2: SET lines=10
                  SET i=1
  • STEP 3: REPEAT STEP 4 to 15 UNTIL i<=lines
  • STEP 4: SET count =0
                  SET j=1
  • STEP 5: REPEAT STEP 6 and 7 UNTIL j<lines< li=""></lines<>
  • STEP 6: IF count is less than (i-1)
                  IF j is not less than (lines-i+1)
                  PRINT j AND INCREMENT count by 1
  • STEP 7: SET j=j+1
  • STEP 8: PRINT 0
  • STEP 9: SET count =0
  • STEP 10: DECREMENT j by 1
  • STEP 11: REPEAT STEP 12 and 13 UNTIL j is greater than 0
  • STEP 12: IF count is less than (i-1)
                  PRINT j AND INCREMENT count by 1
  • STEP 13: SET j = j - 1
  • STEP 14: PRINT new line
  • STEP 15: i = i + 1
  • STEP 16: END

Program:

 public class pattern{  
public static void main(String []args){  
int lines=10;  
int i,j;  
int count;  
for(i=1;i<=lines;i++){// this loop is used to print lines  
count=0;  
         for(j=1;j<lines;j++){// this loop is used to print numbers in a line  
             if(count<i-1){  
                 if(!(j<lines-i+1)){  
                     System.out.print(j);  
                     count++;  
                 }  
             }  
         }  
         System.out.print("0");  
         count=0;  
         for(--j;j>=1;j--){// this loop is used to print j and increment count  
             if(count<i-1){  
             System.out.print(j);  
             count++;  
             }  
         }  
         System.out.println("");  
    }  
      }  
}
